About a year ago I bought some music which came from a Catalan publisher called "La ma de Guido".It struck me that "Guido's mother" was a pretty odd name for a publisher, but then I thought no more about it.Some time later I became aware of my mistake, but that made matters worse; I was even less able to make the connection because, ill-educated buffoon that I am, I lacked a key piece of knowledge.By chance I stumbled upon it yesterday, and now it all makes sense.

(a) Who is Guido?(b) How is his mother relevant?(c) What was my mistake?(d) What piece of knowledge did I lack?(e) How does it all make sense?

(c) My mistake was to assume, by analogy with Spanish "madre", that Catalan "mà" meant "mother".In due course I smelled a rat when I saw that little logo on the front cover which looked like a dirty glove.That made me doubt my assumption and had me going to the dictionary to look up "mà", and sure enough it means "hand".

(d) I had indeed never heard of the Guido's Hand, a gap in my musical education. I offer the fact that I don't sing as a feeble excuse.

(e) Because of the significance of Guido's Hand to the world of music, and indeed because of Arezzo's contribution to the development of music notation, it makes sense for the hand to be adopted as mascot, logo, and even label for a music publisher.

That's easy. Being logicians they would take the question "do you ALL want beer" literally, not pertaining to themselves alone. So if the first two had not wanted beer, they both would have answered NO.

It boils down to simple Boolean logic, with particular reference to deMorgan's laws.

Bearing in mind that, as Chris rightly points out, each logician's answer doesn't state whether he wants beer, but whether they all do, the circumstances in which he can give each of the 3 possible answers are as follows:"Yes": When and only when he wants beer AND knows that both others do too."No": When and only when he does not want beer OR knows that at least one of the others doesn't."I don't know": In all other circumstances.

This third answer therefore indicates (NOT "yes") AND (NOT "no"). Applying the circumstances under which "yes" and "no" may be given, this means:

(NOT(he wants beer AND he knows both others want beer)) AND (NOT(he does not want beer OR he knows at least one of the others wants no beer)).

DeMorgan's rules are that NOT(A AND B) is equivalent to ((NOT A) OR (NOT B))and that NOT(A OR B) is equivalent to ((NOT A) AND (NOT B)).Applying these to the above, we get:

(he does not want beer OR he doesn't know both others want beer) AND (he does want beer AND he doesn't know that at least one of the others wants no beer).

In turn, this is equivalent to:

(he doesn't know the others both want beer) AND (he wants beer) AND (he doesn't know at least one of the others doesn't want beer).

For a logician to answer "I don't know", all three parts of this proposition must be true, in particular the middle one. His "I don't know" answer therefore tells us (or at least the other logicians) that he wants beer.

The second logician now knows the first one wants beer, but doesn't know what the third one wants. Again, his "I don't know" answer indicates that he does want beer.

I have a feeling I've seen this one before somewhere.Yes it can.Betty is either married or not. In both cases the answer which can be deduced is YES.Either married Betty is looking at unmarried Charles, or married Arthur is looking at unmarried Betty.

Chopsticks (music)From Wikipedia, the free encyclopediaFor a different piece of piano music often called "Chopsticks" in the UK, see Der Flohwalzer (the "Flea Waltz")."Chopsticks" (original name "The Celebrated Chop Waltz") is a simple, extremely well known waltz for the piano. It was written in 1877 by the British composer Euphemia Allen under the pseudonym Arthur de Lulli.[1] Allen, who was the sister of a music publisher, was supposedly only sixteen when she composed the piece, with arrangements for solo and duet. ...A group of Russian composers — Alexander Borodin, César Cui, Nikolai Rimsky-Korsakov, Anatoly Lyadov, and Nikolai Shcherbachov (with a modest addition by Franz Liszt) — collaboratively composed four-hand piano variations on this theme for Borodin's daughter Gania.

This curious "toe-tapping" tune believe it or not was a grammy winner in instrumental music. Originally released as "Omkring et Flygel," that is, "Around a Piano." It has classical elements, though if being a grammy winner is a show of popularity, it is then decidely a pop song (though instrumental, most pop songs aren't right?--rare, huh!) Who wrote this song? No cheating and wiki-ing it Every time I hear his name, I laugh, because it sounds like a gag name...

For a better version than my MIDI do-up, hop on over to YouTube and see AllenDale's version

Fact about Meyerbeer: he was a taphephobic (fear of being buried alive) and left instructions that he be placed in his coffin with bells attached to his limbs for him to ring in case of premature burial.

There were two identical twins, one was named Seesharp, the other, Deeflat. Sometimes Seesharp would walk to their grandparents cottage that was 6 miles away up on a hill. Though it was small, you could see the grandparents house from where they lived. One weekend, the twin brothers' mother sent Seesharp to his grandparents house. Seesharp was instructed to go there, and if the grandparents were good and well, then simply to enjoy their company and return home at the end of the weekend. If however their grandparents were unwell, then he should wave his arms outside the house just as the sun set on Saturday. Deeflat's job was to check to see his brother did this or did not. As scheduled, Seesharp made his way to his grandparents place. On Saturday, a great fog befell the countryside. Deeflat looked to the hill to find his brother. Deeflat couldn't see anything. When he returned to his mother and father who demanded an explanation for the expression of bewilderment that rent his face, he said the following:

I couldn't see sharp!
